Abstract:
Highly effective and reusable organophosphorus hydrolase (OPH)-loaded fiber mats have been fabricated that are capable of degrading toxic organophosphates (OPs) over a broad range of relevant concentrations (from 8 to 8250 ppm). The inherent fragility of enzymes, a major impediment in their incorporation into technologically relevant materials, was overcome while retaining their high catalytic efficiency, selectivity, and sensitivity via a random heteropolymers (RHP) approach. Kinetic analysis guides the design of polycaprolactone matrix morphology from films to fibers, facilitating substrate diffusion in the material. The RHP-OPH fiber mats demonstrate excellent stability and reusability with minimal requirements for storage, retaining over 40% of their initial activity after repeated daily use for three months. Practically, present studies provide valuable guidance toward fabrication of enzyme-based functional materials.
